About this project
What does ParaMax add?

ParaMax is a client-side performance mod that cares a bit less about the number in your F3 counter and more about how the game actually feels to play, but doesn't forget about the FPS either. Mod goes after the stutters, hitches, and uneven pacing that make a session feel rough, and it quietly scales its own effort up or down depending on how hard your machine is working at any given moment. You can tweak all settings from inside the game using Mod Menu.
Recommended mods to install alongside:
Dependency:
📖 You're in control
Everything here is a toggle, and the numbers behind it - target FPS, worker threads, culling distances, particle limits, how twitchy the governor is - are all adjustable live from the Mod Menu screen. No digging through JSON. Don't like something? Turn it off. Want the whole thing gone for a moment? There's one switch for that too.
🔧 Presets
Don't want to touch every setting? There are three preset buttons at the top of the config screen:
- Potato PC - you get as many frames as possible. Fewer particles, shorter view distances for entities, less detail far away. It won't look as nice - that's the trade. This is the only preset that watches your FPS and tightens things further when your PC is struggling, then eases back off once you're not.
- Balanced preset - real savings you'd struggle to spot. Particles trimmed, entities and block entities dropped past a comfortable distance, less detail on far-away things. Rain and texture animations are left exactly as they are.
- Lossless Defaults - nothing you can see changes. Culling, particle limits and distant detail reduction are all switched off, but the invisible work carries on: frame pacing is still smoothing out your frames, render objects still get reused instead of getting rebuilt every frame, text still gets cached, and work still spreads across spare cores. So this isn't ParaMax doing nothing - it's ParaMax doing everything that costs you nothing visually. This is how the mod ships, so a fresh install never changes how your game looks, and the button doubles as your config reset for a mod.
Presets aren't modes - they just set the same toggles and sliders you can change yourself. Pick one, then tweak whatever you want.
Frame pacing stays on in all of them. Smooth frames are the whole point.

❓ Something broke?
If you hit a bug or a crash, please open an issue with your log and a quick note on what you were up to. If you can, grab a screenshot of the F3 screen - ParaMax adds a line there showing capacity, pacing, and governor state, and that context makes bugs a lot faster to track down.
Known incompatibilities:
- AsyncParticles
- while exporting video using Flashback render might break, it is recommended to disable ParaMax in the mod menu during that process
